The invention discloses a four-drive hybrid power system based on parallel connection of a super capacitor and an accumulator. The four-drive hybrid power system comprises a four-drive transmission system driven by an engine unit and a rear-drive transmission system driven with the assistance of an engine, and the rear-drive transmission system comprises a motor driving unit and an assisting powerdriving unit which is arranged in cooperation with the motor driving unit; the assisting power driving unit comprises an accumulator unit and a super capacitor unit which are in parallel connection;the accumulator unit provides electric energy for the motor driving unit; when a vehicle is accelerated or climbs a slope, the super capacitor unit is discharged to assist the motor driving unit; whenthe vehicle is decelerated or goes down the slope, the motor driving unit charges the super capacitor unit. By means of the four-drive hybrid power system based on the parallel connection of the super capacitor and the accumulator, energy storage features of the accumulator unit and the deep-charging and deep-discharging features of the super capacitor unit are integrated, the contradiction of instantaneous input and output of energy when the vehicle is decelerated, accelerated or climbs the slope is avoided, and the insufficiency of the accumulator unit in the aspect of instantaneous power input and output is made up for.
